' MACHINE FOR RECUTTING AXLE-SHOULDERS.

SPECIFICATION forming part of Letters Patent No. 547,025, dated October1, 1895.

Application filed December 29,1894- Serial No, 533,273 (No model.)

To aZZ whom it may concern:

Be it known that I, SOLOMON D. NORTH, a citizen of the United States,residing at Plainville, in the county of Hartford and State ofConnecticut, have invented a certain new and useful Improvement inMachines for Recutting Shoulders Upon the Ends of Axle-Arms, of whichthe following is a description, reference being had to the accompanyingdrawings, wherein- Figure 1 is an exterior view of the entire tool. Fig.2 is a view of the same in central longitudinal section on the planedenotedby the broken line m at.

The primary object served by this tool is the recutting of the shouldersat the outer extremity of the axle-arms of vehicles, for the purpose ofpermitting the nut which is commonly borne upon such extremity to beturned up a little farther than was originally intended, so as tocompensate for endwise Wear of the axle-box and cooperating parts. Thetool can also be used for other purposes than that above indicated.

In the accompanying drawings, the letter a denotes an axle-arm to whichthe tool is attached.

b denotes a sleeve loosely inclosin g the axlearm.

0 denotes a key, of which there are three or more, each lying in alongitudinal slot made for that purpose in the sleeve 1), and they areused for centering the sleeve 1) in place upon the axle-arm and thereholding it after it is so centered. These keys are simultaneously andsynchronously moved radially toward a common center by means of thecompressorring d, which is interiorly screw-threaded and has that threadco-operating with a corresponding thread upon the collar 6.

The letter f denotes socket-holes, more or less in number, sunk in thecompressor-ring for the end of a small wrench-bar, whereby thecompressor-ring may be rotated.

The tool, as a whole, is centered and fastened and placed upon anaxle-arm by means of the devices and parts so far described. The forwardportion of the sleeve 19 carries a screwthread I), co-operating with acorresponding screw-thread upon the interior of the feedsleeve g, and itis by the rotation of this feedsleeve 9 upon the axle-arm-inclosingsleeve 1) that the cuttin -tool, soon to be described, is fed back andforth. The feed-sleeve is rotated by any suitable meansfor instance,feed-wheel g.

On the feed-sleeve is hung the rotary toolcarrier h, through the mediumof a flange g on the feed-sleeve and corresponding inclosing parts,which are constituents of the toolcarrier. The tool-carrier has a socket(or it may have more than one) h, carrying a cutting-tool i. The letter10 denotes a wrenchsocket on the tool-carrier for the insertion of awrench-bar to rotate the tool-carrier, and with it the cutting-tool, anddo the cutting for reshouldering axles.

I claim as my improvement In combination, sleeve 19 carrying screwthread19, keys 0, compressor-ring d, interiorly threaded feed sleeve gcarrying flange 9 toolcarrier h rotarily hung on flange 9 tool-socket h,and tool 2', all substantially as described. and for the purposes setforth.

SOLOMON D. NORTH.
